LAM P-STOVE.

SPECIFICATION forming part of Letters Patent No. 520,506, dated May 29, 1 894. Application filed May 8, 1893- Serial lie. 473,568. (No model.)

To all whom it may concern:

Be it known that I, CHARLES S. UPTON, a citizen of the United States, residing in the city and county of New York,in the State of New York, have invented certain new and useful Improvements in Lamp-Stoves; and I do hereby declare that the-following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to lamp stoves, and particularly to that class of combined lamps and stoves which may be used either forheating or illuminating purposes, as desired, being provided with a heating attachment, which may be substituted for the ordinary transparent glass chimney, used when illumination is desired; and my invention is an improvement on another lamp-stove of the same class invented by me, and which forms the subject matter of an application for Letters Patent, filed February 4, 1893, Serial No. 460,966.

The object of my invention is to provide a heating attachment for lamp-stoves of the class above described, which while being light and simple, and cheap of construction shall yet be strong, and capable of sustaining considerable weight upon its spider or grid, without injury to either the heating attachment itself, or to the lamp. This object is attained in the invention herein described, and illustrated in the drawings, which accompany and form part of this application, in which the same reference numerals indicate the same or corresponding parts, and in which- Figure 1, is an elevation of the lamp-stove, showing the heatingattachmentapplied thereto. Fig. 2, is a similar view in which the heating attachment has been removed, and a glass chimney substituted therefor, the stove being then adapted for illuminating purposes.

In the drawings, 1 is the base or oil-tank of the stove, supplied with the usual filling orifice, and with .the burner 2, and wick adjusting device 3, the burner being of the central draft class, such as is used on the well known Rochester lamp. I do not, however, limit myself to the use of this particular burner, nor to this particular class of burners, though they are especially well adapted to the purpose, on account of the large amount of heat given out. The burner is supplied with the usual chimney supporting collar 4, having the springs 5, for holding the chimney in place.

The heating attachment, shown in Fig. 1, consists of a chimney 6, which is preferably of metal, and may be supplied with a hinged door filled with transparent material, which thus gives ready access to the lamp for lighting and extinguishing the same, and likewise permits some light to escape into the room. To the lower end of this chimney is secured a collar 8, of a size adapted to rest upon the chimney supporting collar 4, and to be held in place by the springs 5, as shown.

Upon the top of the chimney 6 is placed the spider or grid 7, which is of the usual construction. Secured to this grid 7, are vertical rods or pillars 10, the ends of which rest upon the base 1, of the lamp, passing through apertures in braces 9, secured to and projecting radially from the collar 8. These rods or pillars 10, are intended to carry the weight of the heating device, with whatever article may be resting on the grid, the chimney supporting device of the burner merely serving to hold the heating device in position. Since the rods or pillars 10 must necessarily be of considerable length, and might bend or buckle were the load applied at the top-alone, I have made the chimney 6,. with the collar 5, and. projecting braces 9, of considerable strength, and the ends of these braces rest upon shoulders 11, formed upon the ends of the rods or pillars 10, the weight, or a large portion thereof, being thus transferred from the grid through the chimney 6, collar 5 and braces 9, to the rods 10 near the lower ends thereof, thus preventing any buckling of these rods. The shoulders 11, may be in one piece with the rod 10, but are most cheaply and easily formed, by slipping tubular sleeves of the proper size over the rods 10, while assembling the heating device.

While I have shown the rods 10, as straight, it is not essential that they should be so, and in order to make the heating device more compact, it may be advisable to carry these rods 10, inward at a point just above the braces 9, so that they will lie very close to the chimney 6. This can, however, be done with-' out departing from the scope of my invention.

In using this lamp-stove, it will be seen that in order to adapt it for heating purposes, all

that is required is to remove the glass chimney used for illuminating purposes, and to substitute therefor the heating device above described, the collar 8, fitting into the chimney supporting device of the burner, in the same manner that the glass chimney just removed formerly fitted.

Having thus completely described my said invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, With a lamp having an ordinary burner 2 and chimney support 4, of a heating attachment consisting of a chimney 6, having a collar 8 at the lower end thereof, adapted to enter the said chimney support and to be held in place by'the springs 5, a grid 7 at the top of said chimney, rods or pillars 10 attached to said grid and resting upon the body of the lamp, and braces 9 for said rods or pillars, attached to and projecting radially from said collar 8, substantially as described.

attached to and projecting radially from said collar, and resting upon shoulders 11 of said rods, substantially as described.

3. The combination, with a lamp having an ordinary burner provided with a suitable chimney support, of a chimney adapted to fit such support and provided at its upper end with a heating spider or grid, radial braces 9 attached to the lower portion of the chimney, and rods or pillars 10, passing through the ends of the braces 9, and supporting the spider or grid by resting upon the top of the lamp body, substantially as described.

4:. The combination, with a lamp having an ordinary burner provided With a suitable chimney support, of a chimney adapted to fit such support, radial braces 9 attached to the lower portion of the chimney, rods or pillars 10 supported by the top of the lamp body, passing through and supporting the braces, and a heating spider or grid supported at the top of the chimney by the said rods, substantially as described.

Signed at the city and county of New York, in the State of New York, this 6th day of May, A. D. 1893.

CHARLES S. UPTON.
